The meshing gears 6, 9 and 1l, 14 are covered by casing parts 27, 28 respectively, removably secured by screws 29. The shaft or wolf-'receiving member 13 has suitable means as the socket 30 in its end, for mounting the desired rotary tool, such for instance as the screw driver 31, the end 82 of which is received into said socket.

Openings 33, 34 are made inthe bearing members 1, 3 into which a rod or punch mayV be inserted for driving out the key pins 35, 3 whereby the bevel gears are held on their shafts; vThebearing member ldesirably has a diametri'cally enlarged surrounding` handle portion 37 as shown in Figure 1.

`It Will be seen'that this device 1s adapted` v for use on work in positions` difficult or imagainst interrelative turning movement comprising teeth on one of the bearing members circularly disposed aboutits axis, a sleeve part of the other bearing member non-turnable thereon and having circular-ly disposed -teeth adapted to engage the first-mentioned teeth, and a collar on one of the bearing me1n bers engaging said sleeve part and threaded on the other bearing member, and turnable around .said members to move said sleeve part andV cause its teeth to engage the first-men tioned teeth.
